EV charging station: Off grid mode how to check?

Can anybody tell me how to check if EV charging station with firmware 1.25 is in off grid mode?

I have trouble using auto mode and fear that not being in off grid mode is the reason for that.

Hi, can you describe your system?

It is a little bit special:

My system is totally off grid.

On the AC in of my Multiplus (EasySolar) is a Smart Phoenix connected. So they are both daisy chained. The smart Phoenix is defined as a “Generator” and constantly running. When there is more power demand than the Phoenix can deliver, the Multiplus adds this power using power assist.

I think this is not very common ;-)


My EV charging station (and my house) is connected to AC out of the Multiplus.

Phoenix and Multiplus are connected to the same Battery. There is also a Cerbo and a Lynx shunt in place and two smart Solar MPPT.

Also there is a Carlo Gavazzi Grid meter for measuring consumed grid power, but grid is not connected to my system!

Yes, it is a special system :)
as you can see, it detects power flowing on AC In, and because of this, it is considered grid connected. Please test it again without and share the results

Is there a way to force off grid mode with my configuration?

Because i‘m using two 48/3000 devices, disconnecting my phoenix from AC in will cause my Multiplus to be overloaded too often.
